WRENCH.

Application filed September To all whom it may concern:

Be it known that T, J osnrn F. PONTIUS, a citizen of the United States,and a resident of Hot Springs, in the county of Garland and State ofArkansas, have invented certain new and useful Improvements in l irenches, of which the following is a specification.

This invention is an improvement in wrenches and particularly inwrenches especially designed for use on wagons; and the inventionconsists in certain novel constructions and combinations of parts aswill be hereinafter described and claimed.

In the drawing Figure 1 is a perspective view of a wrench embodying myinvention. Fig. 2 is a cross section thereof, and Fig. 3 is a partialvertical longitudinal section of the wrench.

The wrench is especially designed for use as a draw pin on wagons, thehandle bar A being adapted for such purpose, and this handle bar carriesat its upper end a body B. While the body B might be made integral withthe bar A, it is preferred to make it separate as shown, and to providethe said body with a longitudinal opening B, in which the stem A. of thebar A is held by a rivet head A as best shown in Fig. 3 of the drawing.By this construction the handle bar A can be readily replaced when wornor otherwise injured. The head B has the hammer head projection B on oneface and is provided with the laterally projecting knuckles B arrangedin pairs and spaced apart to receive between them the knuckles C of thejaws C, said knuckles B and C having registering openings receiving thepintle D which completes the hinge connection between the jaws and thehead B of the wrench. These jaws C may by the hinge connection be spreadand contracted to fit bolts or nuts of different sizes, and their innerfaces are provided near their outer edges with beveled portions G whichapproach a parallel position when the jaws are nearly closed as will beunderstood from Fig. 2 of the drawing.

The jaws are connected by a cross bolt E,

having a head E outside of one of the jaws C, and extending thenceacross the space between the jaws and through an elongated opening C inthe opposite jaw and receiving a wing nut F, the pointed end FF of thebolt being slightly headed to prevent accidental displacement of the nutafter the latter has been turned on the bolt. This is'best shown in Fig.2.

By tightening the nut F the jaws may be adjusted toward each other tofit a smaller nut or bolt, and a. spring G on the bolt between the jawsC and bearing at its ends against washers H, operates to open the jawsas the nut F is slackened.

The wrench is especially designed for use in wagons for the wheel nutand eliiciently serves the purpose for which. it is designed.

The bolt E has a squared portion E adjacent to its head E and theopening receiving the said squared portion is correspondingly formed toprevent the turning of the bolt.

A tool for use as a wagon draw pin consisting of the wrench hereindescribed comprising a head having a body portion and a hammer headprojecting rearwardly therefrom, the body portion being provided withspaced apart lateral knuckles at its opposite edges and in fixedrelation to the body per- I tion, the latter also having in a line withthe hammer projection and with a line ll'll(l way between the knuckles,an opening ere tending in a direction pa allel to the pivotal axes ofjaws pivoted to said knuckles, the jaws pivoted to the knuckles andprojecting in an opposite direction from the hammer head, the pivotalaxes of the jaws being in fixed relation to the body portion, a handlebar having a stem held at one end in said opening of the wrench head andstraightand unobstructed at its other end, and a spring device ope'ating between the jaws, substantially as set forth.
